Some people wear jewelry and have allergic reactions, itchy skin, and some even have redness and tingling, so they have to go to the hospital. These are because allergic contact dermatitis is usually an allergic reaction caused by people who are allergic to some metals, such as nickel and chromium, and some only have allergic symptoms in the parts where jewelry touches the skin, such as neck, wrist and fingers. But some people with severe allergies will have systemic allergic reactions. First, it will be red and swollen, then the skin will start to appear small papules and blisters, and the whole body will itch and feel uncomfortable. It may happen if it is not treated in time.
Patients with allergic reactions are all caused by wearing metal jewelry, especially low-grade K gold decorative jewelry, while other pure gold and jade jewelry will not cause allergies.
Some people are worried about whether there is radioactive radiation in jewelry and jade jewelry, and experts from the most authoritative jewelry testing institutions in China deny this.
Li Jingzhi, a senior engineer of the National Jewelry and Jade Quality Supervision and Inspection Center, said: "The blue topaz or topaz sold in the market (according to the detection in our laboratory) has no residual radioactivity, so it is harmless to human body."
You can wear whatever you want, but you'd better take off all your jewelry before going to bed at night.
